The optical fiber decoration device is characterized by having an LED light source consisting of a plurality of LED&#39;s which are arranged at an end of optical fiber for emitting one or more colors and partially superimposed, enabling synthesis of colors. In FIG.  1 , the optical fiber decoration device (I) includes an LED light source unit ( 2 ) and an optical fiber ( 1   a ). The distance L between the LED light source ( 2 ) and the optical fiber is 5 to 100 mm. Red, blue, and green LED&#39;s are used to realize multiple colors. The optical fiber decoration device can be used for signboards, outdoor decorations, bus advertisement, indoor decorations, decorations in an aquarium, unit type Christmas trees, clothes, and the like.

FIELD OF INVENTION

This invention relates to optical fiber decoration devices.Specifically, it relates to optical fiber decoration devices using LED(light emitting diode) as a light source and decoration items usingthese devices. The light source can emit multiple colors, has a longlifetime and low power consumption, is very safe, and has a fantasticappearance.

BACKGROUND OF THE INVENTION

Recent years have seen the development of decoration items using lights,the light source being lamps or the combination of lamps and opticalfiber, to decorate Christmas trees and advertising boards. For instance,in the case of general Christmas trees, the effect of the decoration hasbeen achieved by means of blinking or continuously light colored bulbsthat were mounted to branches and treetops of natural and artificialtrees. In order to change the color, a technique was applied byinserting a colored translucent medium, such as the colored glass orcolored cellophane, between a lamp of the light source and the lightentrance of the optical fiber ends and letting the light pass throughthis translucent medium and illuminate an optical fiber.

The decoration item, like the above-mentioned, can be dangerous becausefire can occur due to the heat of the lamp and the adaptor, since ituses a lamp with high power consumption. This results in not only acomplex waterproof design but also a higher cost. When miniaturizing theitem, it is difficult to use a battery and hence has poor portability.Lamp has faults such as a short lamp lifetime and high rate ofgenerating defective goods due to the failure from accidents duringtransportation. Therefore, the optical fiber decoration device usinglamps as a light source has the problem on restrictions of the usage andthe place. On the other hand, when a large-scale decoration item isproduced, for instance a Christmas tree, the length of optical fibersbecomes long from the light source when a lamp is used as the lightsource. In this case, there is a problem that the brightness from theother end decreases because the attenuation of light occurs when passingthrough an optical fiber. When an electric decoration was attempted onclothes, the optical fiber decoration device using a lamp as the lightsource does not allow wearing for a long time as well as has a poorportability due to the heat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following context, this invention will be explained morespecifically with figures. FIG. 1 shows a cross-sectional diagram whichthe basics of the optical fiber decoration device of this invention. InFIG. 1, the optical fiber decoration device described in claim 1 of thisinvention is characterized by that multiple LEDs emitting at leastmonochromatic or polychromatic light are installed at the end of theoptical fiber, and has a LED light source these which enable the colormixing by overlapping of some of these colors. The optical fiberdecoration device I consists of a LED light source unit 2 and an opticalfiber 1 a. In order for a LED light source unit 2 to emit light, it isnecessary to connect a controller (refer to FIG. 5) to the LED. Thus,that the LED light source emits light means that not only a controlleris used but also a controller is integrated with the LED light source.

The optical fiber 1 used for this invention is the one that the lightpasses through within fiber, light enters from one end of the opticalfiber and is emitted from another end. The diameter of the optical fiber1 is 0.4–0.5 mm, and 0.1–0.3 mm is preferable. The optical fiber bundle1 a which bundled this optical fiber 1 consists of 10–30000 opticalfibers 1. 100–30000 is preferable and 100–20000 is more preferable.Optical fiber is usually formed so that light may not leak from theperimeter wall. In this invention, optical fibers are constructed toallow light leaking from the perimeter wall at regular or irregularintervals. For example, a crack may be created in the perimeter wall toallow the light leakage from there. The crack may also be a point, aline, or a spiral line. The distance between the LED unit 2 and theoptical fiber 1 a, being referred to as L, is 5–100 mm preferably. SinceL changes with the kinds of the LEDs and the luminosity, it is desirableto determine the optimal distance using a simple test before it is used.As one example for the configuration to maintain the distance L and theconnection between the LED unit 2 and optical fiber 1 a, an arrangementto maintain the distance L is desirable after one end 1 b of the opticalfiber bundle is bonded to form a joint 4 using an adhesive.

Although the optical fiber decoration device I of this invention can bearranged one or more LEDs, it may be desirable to arrange three LEDswith different colors. The most desirable example is shown in FIG. 3.FIG. 3 shows a perspective diagram of the example of the mixing colorsof red, blue, and green. In FIG. 3, the LED unit 2 is formed bycontaining three LEDs of red LED 2 c, blue LED 2 a, and green LED 2 b inthe container 5. This unit 2 emits three primary colors, emits light inyellow 2 bc by red 2 c and green 2 b, emits light in bluish green(cyanogen) 2 ab by blue 2 a and green 2 b, and emits light in purplishred (magenta) 2 ac by red 2 c and blue 2 a. The way to emit light ofthree primary colors was explained in the example of this invention,without being limited to these, two or more different colors may beoverlapped partially, thereby, countless mixtures of colors can beobtained. The illumination angle (θ) of a LED lamp used as a LED lightsource (hereafter called a lamp also) depends on the diameter of the LEDlamp. For example, when the diameter of this lamp is larger than 2.5 mm,the desirable illumination angle (θ) is 10–50 degree. In this case, theinterval of the multiple LED lamp of 0–15 mm is desirable. A few tomultiple colors can be created by making the distance from the point ofa LED lamp emitting light to the light entrance of an optical fiberlarger than the intersection of illumination lights. Although in theseexamples, the light sources are fixed, when a LED light source is movedforward and backward, or it is moved while rotating, it can createcountless colors by the motion (refer to FIG. 15 b) even if the distanceof the illumination light is below an intersection.

When the diameter of a LED lamp, for example, is less than 2.5 mm, theillumination angle of 0–35 degree is desirable. The interval of multipleLED lamps is 0–15 mm, similar to the case that the diameter of the LEDlamp mentioned above is over 2.5 mm, a few to multiple colors can becreated by making the distance from the point of a LED lamp emittinglight to the light entrance of an optical fiber larger than theintersection of illumination lights. Although the above examples arelight sources that are fixed, when a LED light source is rotated, it cancreate countless colors by the motion even if the distance of theillumination light is below an intersection. Especially when a LED lampis moved back and forth or rotated, that is, making a LED lamp move(such as up and down, left and right, slant, etc. with proper angles,back and forth motion, or regular and irregular rotation), one, a few tomany colors can be created. In this invention, controls of blinking,2-color control, 3-color control, etc. can be performed by combining anemitting control device with the optical fiber decoration device. Somearranged LED lamps can blink regularly or irregularly, and they can bemade dark or bright by gradually weakening and strengthening theluminosity. The color from an optical fiber using such a LED lightsource can be varied. This control device is made by mechanical control,for example, a control rod is rotated by a motor and the electricalcontact and non-contact. It is also controllable using electricelements.

The optical fiber decoration device described in the claim 2 of thisinvention is characterized by integration of the end of an optical fiberwith the head of LED. FIG. 2 is a cross-sectional diagram showing theoptical fiber decoration device. As shown in FIG. 2, integration of theoptical fiber decoration device (refer to II) was formed by insertingand fixing a cylinder 5 into the head of a LED, and then inserting lightentrance of optical fiber bundle 1 a in the upper part of a cylinder 5.Another variation is that the adhesion part 4 is formed by inserting aLED 2 into a cylinder 5 and bonding bundle 1 a of an optical fiber 1with an adhesive. When the upper surface of the LED is round, bundle 1 aof an optical fiber 1 may be pasted along the circular side. Fordecoration, LED may be desired to emit monochromatic light, any threeprimary colors, as well as any colors by mixing two or more colors.Arbitrary colors can be arranged into the required part of thedecoration by this composition.

Because the optical fiber decoration device described in the claim 3 ofthis invention is characterized by arranging a condenser lens betweenmultiple LED light sources and the optical fiber, the luminosity of theLED light source, or the luminosity from LEDs to an optical fiberbundle, can be increased. FIG. 4 is a cross-sectional diagram showingthe optical fiber decoration device with a condenser. In FIG. 4, theluminosity is increased by increasing the number of LEDs 2, and a lens30 is inserted between the optical fiber bundle 1 a and the LED lightsource 2 to collect the LED illumination. The illumination is condensedinto the light entrance 1 b of an optical fiber bundle 1 a with thislens 30. Consequently, the luminosity at the light entrance of anoptical fiber increases, so the light emitted from the tip of an opticalfiber becomes very bright. According to the kind of lens, the brightnesscan be adjusted by increasing the brightness of a LED light source, orchanging the width and the illumination angle of the beam. As for lens,the change in light can be achieved by scattering light using a speciallens, for example, a lens with facet-cut surfaces. In addition, the beamemitted from a LED lamp can be controlled by a lens, it can be set up sothat LED lamps may blink or change colors by interlocking with one ormore IC boards using the above-mentioned controller, and LED lamps canblink and change colors accompanying the sound and rhythm of music.

The optical fiber decoration device described in the claim 4 of thisinvention is characterized by that the luminosity of singular ormultiple LEDs can be at least gradually changed. The optical fiberdecoration device described in the claim 5 of this invention ischaracterized by that multiple colors can be created that is addedcolors to mix by independently changing individual luminosity of themultiply LEDs. In the invention described in the claim 4 and 5, theemitting color (mixed color) can be controlled by decreasing orincreasing the luminosity of more than two kinds of LEDs, using theemitting control device to control LED luminosity. The decorative effectcan be enhanced by blinking the LEDs. Blinking can be formed by thecombination of one, two, three, or various colors in the case of manycolors.

The optical fiber decoration device described in the claim 6 of thisinvention is characterized by controlling the LED luminosity with amicrocomputer. Operations of changing luminosity and blinking usingmicrocomputer technology can be carried out by the optical fiberdecoration device, described in the above-mentioned claim 4 and 5. Thiscontrol circuit can be carried out using either mechanical or electricmethods, and can use well-known technologies in this technical field. Tochange the emitting color or the luminosity one can manually switch theoptical fiber decoration device described in the claim 7 of thisinvention. In this case, to change the pattern of the luminosity one canchange the luminescence control circuit with a manual switch, or changethe software controlled by a microcomputer. For example, LEDs arearranged so that each color of the red, blue, and green LEDs may overlappartially. A switch is installed for these LEDs so that the desiredcolor can be obtained by switch operation, switch on or switch off. Ifred LED is turned off, an overlapped color that is yellow color can beobtained by mixing lights from the blue and green LEDs.

The optical fiber decoration device, described in the claim 8 of thisinvention, can carry out switching according to the signal from a sensorby the manual switch described in the claim 7. The sensor used in thiscase is characterized by changing luminosity controlled by the detectionof sound or light. For example, a sensor for detection of sound or lightis installed in the optical fiber decoration device, and theluminescence pattern is controlled by a microcomputer program accordingto the signal detected by the sensor.

The optical fiber decoration device, described in the claim 8 of thisinvention, is characterized by using a unit integrated from the opticalfiber decoration device with the LED power supply. In the optical fiberdecoration device I in FIG. 1, the optical fiber decoration device Ishown in FIG. 2, and the optical fiber decoration device in FIG. 4,controller 6, luminescence controller 8, and power supply 7 areconnected in the optical fiber decoration device II as shown in theblock chart in FIG. 5. Among these, controller 6 is sometimes built inand integrated with the optical fiber decoration device, and sometimesarranged separately with the optical fiber decoration device. Here, thecontroller 6 is used to control the emitting of the LED light source ofthe optical fiber decoration device. The luminescence controller 8 isused to control the luminosity after the event when the LED light sourceemits light. For example, it can be controlled by increasing anddecreasing the luminosity or by blinking. Therefore, the integration ofthe optical fiber decoration device 1I with a power supply 7 naturallymeans the integration of a controller 6, a luminescence controller 8,and a power supply 7.

A power supply 7 is used as a LED power supply, such as a battery or astorage battery. It is desirable to integrate the optical fiberdecoration device, the controller 6, the luminescence controller 8, andpower supply 7 as a unit. For example, making them into a unit requiresintegration of an optical fiber, LED, a controller, a luminescencecontroller, and a power supply in a container or a case. Not to mention,a switch to supply to the optical fiber decoration device and cut theelectric power, has been installed.

The optical fiber decoration device, described in the claim 10 of thisinvention, is characterized by using a power supply obtained from asolar cell as a power supply for LED. It is advantageous to use a solarcell as a power supply since a LED has little power consumption. Whenusing a solar cell, it is desirable to charge a supplemental storagebattery for a solar cell, and then use the storage battery as a directpower supply. FIG. 6 is a circuit diagram showing the example to use thesolar cell for the power supply. In FIG. 6, the optical fiber decorationdevice II is connected with the storage battery 9 and the solar cell 10.In the optical fiber decoration device II, the electric power issupplied by storage battery 9, the storage battery 9 is supplied by asolar battery 10, which is charged in daytime.

At least a part of the optical fiber decoration device, described in theclaim 11 of this invention, is waterproof. The waterproof method is tobuild a waterproofing structure by filling up and covering with resin tomake the part watertight in LED light source. For example, the wholepart of a LED light source, except the optical fiber in an optical fiberdecoration device, is made waterproofing (that is, the whole LED lightsource) by covering with resin. FIG. 7 is a cross-sectional diagramshowing an example of the waterproofing structure of the optical fiberdecoration device of this invention. FIG. 7 shows a cross-sectionaldiagram of waterproofing of the optical fiber decoration device shown inFIGS. 1 to 4. In FIG. 7, the lower part of the LED light source, exceptthe optical fiber of optical fiber decoration device, is inserted in aprevention connector 11, and a code 12 extended from this connector 11is connected to the waterproofing case 13. The waterproofing case 13contains the luminescence controller 8 and the power supply 7. When apower supply 7 uses a battery, in order to exchange a battery, a lid isinstalled in a waterproofing case and the lid can be opened for thebattery exchange. In this case, not to mention, the opening and shuttingpart of the lid is made watertight.

There is a cavity 14 a inside the trunk 14 and thebranches 15. The optical fiber bundles are distributed to this cavity 14a according to the number of branches 15, the tip of an optical fiber isexposed at the branch tip along each branch 15. The exposed tip may beexpanded into a flower shape 19 of the morning-glory. On the other hand,a plinth 17 contains the LED light source 2, the luminescence controller8, and the power supply 7. At the upper part of the LED light source 2,a bundle of optical fiber (1000 beams/bundle) 18 a is installed at theposition of L=10 mm from the light source. The tip of this optical fiberbundle 18 a is distributed into a proper number along each branch, andis further divided into 40–50 beams at the tip of a branch.
